wooden elave pipe and branches to warm water cold water and wheeler creeks WOODEN PIPE the wooden save pipe extends from the intake at the of wheeler creek in ogden canyon to a point nearly opposite the powder mill dam and from the mouth of ogden calyon to the reservoir on nob hill it is composed of sixteen staves mill dressed from two by six inch redwood foists joists each stave is about five and three quarter SO inches wide and one and nine sixteenths 1916 19 16 inches thick and is so dressed that when formed into a pipe the inner circle is twenty four inches in diameter the pipe is laid continuously in the trench without joints the lap at the stave joints being two 2 feet and over and is banded by oue balf 1 inch mill deteel bands fastened by a cast iron saddle the wooden staven were not coated on either their internal or external surface but the steel bands were protected by au asphalt coating and the threaded enus were afterwards painted with P and paint the wooden kotave pipe line is so located that about ninety five 95 per rent of its entire length ie considerably below the hydraulic gradient Rr adient which insures the pipe of being not only continuously lull of water but under an internal pressure varying from a few feel heasto nearly seventy 70 feet head ao 10 consideration of the fact that this wooden stave pipe has been in operation for nearly eight 8 years its present condition is excellent we have tin covered portions of the pipe throughout its entire length in at least forty 40 different places an d have found without exception the redwood of which the staves are composed ta be in a sound condition it is true that owing to the lack of the necessary care and attention the wood baa deteriorated at the outside in those portions where the melting snows and rain borms have removed the covering of earth and thus exposed to be action of the sunlight and but even in such por tons the injury to the wood seems to be of little consequence STEEL BANDS the asphalt coating of the steel bands eema to be partially removed in places but in no instances did we find more than specks of rust on their surface since only about one fifth 15 1 5 of ahe 1 each baud is required to inthe internal it is be bat any c erosion in the bands will riot ma serially affect for many years at least the efficiency of the pipe the overloading of this boodea auve pipa by aarti and rocks removed from the trench of the six 6 foot pipe laid by the phonier power j is ot a more serious character and may do much injury to the smaller pi ap pp the i water pipe is now covered with such earth and rock to a depth of from twelve 12 feet over distances aggregating many hundred feet and if at any time either a part al va aum is formed the pipe or tie material which has recently been placed above it saturated with batera collapse of the stave pipe would to be inevitable i 1 the wrought iron riveted pipe extends from a point neatly opposite the powder mill dam to the mouth u ogden canyon it is twenty tour 21 inches internal and is composed in part of iron 1 2 gauge in and in the lowest coition poi tion of the dip below W i G wilsons baw mill of iron no 10 1 gauge in thickness the apama are double riveted and tte round seams single riveted while each length ia connected with he adjacent length either by a riveted or by a lead joint ihie pipe is also found to be in good the earth covering from many portions por tiona waa removed and the pipe inspected by ue la some placed the asphalt coating was partially if not wholly removed bat evan in such places the metal allowed

company has in much damage to the intake on ogden river ASI the bridges and tre etlea and other structures along toe route of the conduit are all in a eafe condition but allow diens of needed repair the brides in particular were bui t in midwinter mid winter cf preen lumber anil the various wooden members lave contracted to euch an extent as to cause a slight instead of atie camber defects should

tu be used it need be by the iri gators this arrangement y entirely belf regulating aad sub serves the twofold burpoe of economizing writer and supplying the city with an abundant water supply in cabes of emergency all fittings and appliances pertaining to this overflow were found to be in a satisfactory condition the nob aill reservoir buila in 1891 a designed to bold U S billone ei llone but owing to the deposition of clay and Ee diment over the bottom during abe subsequent period its capacity line been deduced educed to approximately U S gallons the embankment bypass by pass inflow and outlet pipes valves fittings and fence are all in apparently good condition mie chief defect in thia distributive reservoir is the lack of either a rement ur asphalt lining the wooden lining which now extends part way down the water slopes does not holly prevent wash in the embankment near alie water level and since the bottom of the reservoir and the lower portion of the water elopes are entirely unprotected by any lining it is well nigh impossible to properly aban the reservoir at regular periods of time the present distributive system of w ater maina for city was laid for the mast part from june to november of 1890 and now comprises about thirty miles of pipe which varv in eize bom awn 2 inches to twenty 20 inches in diameter the feed main on twenty fifth street consists of wrought iron pipe coaled with asphalt and the balance of the distributive system with the exception of the two inch pipe consists of cheel piping protected by the kalamein process and by a coating of asphalt the time of purchasing the kalaman piping the merits of this then comparatively new kind of piping were fully investigated by both the officers of ogden ci and the direct ora of toe B liand K W V and irrigation co and favorable report made heron in all likelihood favorable report on kala india piping induced tho water works company to purchase this kind of material contrary to the advice of their engineers who recommended 1 iron pipe as may be by the following extract ol 01 a report made by the engineers to the company and dated feb 1890 1 I have already expressed preference for cast iron pipe it bas been longer before the public and is universally regarded and reliable an important factor in case water works bonds are to be floated this reboil was signed by the engineer harge and concurred by the consult ng engineer ane kalamein piping is connected by means of the converse loik joint this mode of coupling less lead and oakum than ie quiren qu ired in making in cast irn pipe and is more dieal y copied opi ed but has not the strength of a cast iron jointe the internal pressure of the water is liable to force out ahe lead packing and cause leaks from november to october 1891 there occurred in ahe converse lock joints of the kala racin piping of the dadeo water works system 13 slip joints in all of which ane lead packing wae more or less forced out of the jonte the surface of the water in the re of the ogdan city water works is at au elevation of feet washington avenue and street is at an elevation of feet thus chiv ing an available pressure of pounds per inch the is regulated by two automatic pressure reg ii lalore and located at the intersection of cuylor avenue and street and I 1 tho other near jefferson avenue and j twenty fifth street BO eliat the pressure at washington avenue and street is usually about from 80 to pounds per square inch and can be increased to pound should necessarily demand possibly the fluctuations of these regulators together with the water mm account for great many of 1 leaks in the joints we are not enabled to report upon the condition of the distributive getem further at present and suggett that you obtain permission to uncover pipe that the fame may be youre respectfully 8 consulting engineer N W BETHEL city engineer |
